Date: Wed, 4 Jan 2012 19:46:42 -0500 From: Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> To: linux-kernel@...r.kernel.org, jbarnes@...tuousgeek.org, linux-pci@...r.kernel.org Cc: xen-devel@...ts.xensource.com, Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> Subject: [PATCH 4/5] xen/pciback: Expand the warning message to include domain id. When a PCI device is transferred to another domain and it is still in usage (from the internal perspective), mention which other domain is using it to aid in debugging.
